The stopper 27a is fixed to the camera body 1. The locking plate 25 functions to lock the imaging unit 2 in cooperation with the locking target claw 20d which is the locking target member. The unlocking mechanism 24 'is outlined by a unlocking operation member (unlocking plate) 26 (see FIGS. 17 and 18), a spindle 27, and a stopper 27b. The stopper 27b is fixed to the camera body 1. The unlocking operation member 26 functions to release the imaging unit 2 locked to the camera body 1 by the locking plate 25.

When the camera body 1 is viewed from the front, the unlocking operation member 26 is provided at a position similar to that of the release button of the interchangeable lens barrel unit of the conventional single-lens reflex camera. Therefore, even a person familiar with the conventional interchangeable lens barrel type single-lens reflex camera can easily perform the separation operation of the imaging unit 2, and the possibility of misoperation is low. Therefore, the camera body 1 which can isolate | separate an imaging unit easily can be provided, reducing the risk by malfunction.

As shown in Figs. 15 and 16, the locking plate 25 has a shaft hole 25a, a notch 25b, and a locking claw 25c. Spindle 27 (see FIGS. 13 and 14) passes through shaft hole 25a. When the direction from the rear side to the front side of the camera body 1 is defined as the front, the claw tip 25c ″ of the locking claw 25c is facing forward. In the state arranged in 1A, the claw tip 20d '(see Fig. 14) of the locking object claw 20d faces in the direction facing the rear wall portion 1B, namely, the front side of the camera body 1. When the direction from the back toward the rear side is defined as the rear side, the claw tip 20d 'of the locking object claw 20d faces backward.

The locking plate 25 rotates around the spindle 27 and is pressed forward (by the arrow F3 in FIG. 14) by the pressing means (not shown). The stopper 27a serves to regulate the rotation stop position of the locking plate 25 by the pressing means. When the locking claw 25c and the locking object claw 20d are not engaged, the locking plate 25 is held in contact with the stopper 27a by the rotation and pressing of the pressing means.

The unlocking operation member 26 is separated from the stopper 27a. The inclined wall 25c 'is formed in the locking claw 25c. When attaching the imaging unit 2 to the camera body 1 by moving the imaging unit 2 from the right side to the left side with respect to the camera body 1, the inclined wall 25c 'is engaged with the inclined wall 20e. Then, the locking plate 25 is rotated backward by using the spindle 27 as a supporting point.

As shown in Figs. 17 and 18, the unlocking operation member 26 has an axial hole 26a, a release projection 26b, a locking projection 26c, and a unlocking button 26d. The spindle 27 which rotatably supports the locking plate 25 passes through the shaft hole 26a. The spindle 27 is inserted into the shaft hole 25a and the shaft hole 26a and fixed to the camera body 1.

The release protrusion 26b serves to rotate the locking plate 25 in the release direction (the opposite direction to F3) in contact with the side surface 25f of the locking plate 25. One end portion 28a of the unlocking spring 28 is caught by the locking projection 26c. The other end 28b of the unlocking spring 28 is caught by a locking projection (not shown) provided in an appropriate portion of the side wall portion 1C. The unlocking spring 28 serves to rotate and deflect the unlocking operation member 26 toward the front with respect to the spindle 27.

The stopper 27b plays a role of regulating the rotation stop position of the unlocking operation member 26 due to the rotational biasing force of the unlocking spring 28. The unlocking operation member 26 is in contact with the stopper 27b at the time of non-operation. At the time of operation of the unlocking operation member 26, the unlocking operation member 26 is moved away from the stopper 27b and rotated in the direction toward the stopper 27a. The rotation of the unlocking operation member 26 in the operation direction is regulated by the stopper 27a.

As shown in Fig. 1 and Fig. 2, when the side where the upper wall portion 1D is present is upward, the unlocking button 26d is located above the finger-hanging recess 1c ". The hook recess 1c "is located under the unlocking operation member 26. As shown in FIG. The unlocking button 26d has a finger rest portion 26e protruding outward from the grip portion 1c.

The upper portion of the grip portion 1c is usually a position which does not prevent the user from holding the grip portion during shooting. Since this position does not easily allow unintended operation, it is possible to provide a camera body that can easily detach the imaging unit while further reducing the risks due to misoperation. Further, since the unlocking operation member 26 is provided at a position above the grip recess, which is a place where the user's finger is less likely to touch when the grip convex portion is gripped, the risk of misoperation can be further reduced.

In this embodiment, the unlocking button 26d is rotated along the outer shape of the grip portion 1c. The locking plate 25 and the unlocking operation member 26 overlap each other, and are rotated by using the spindle 27 as a support point. The locking plate 25 is rotated in approximately the same plane as the rotation plane of the unlocking button 26d.

In addition, as shown in Figs. 26 and 27, when the bent portion 4f is located inside the imaging unit 2 with respect to the engaging plate portion 10n, regardless of the presence or absence of the engaging projection 4g, With the imaging unit 2 inclined with respect to the rear wall reinforcing sheet metal member 4 for the body of the camera body 1, there is no possibility that the two connector portions 11 and 12 are connected.

With the imaging unit 2 properly attached to the camera body 1, that is, with the imaging unit side connector 11 and the camera body side connector 12 connected to each other, a pair of coupling claws 4b, 4b) may contact the contact plate portion k7.

As shown in Figs. 24 to 26, the inclined elastic plate portions k5 and k6 in the state where the coupling plate portions 10n and 10n of the rear wall reinforcement sheet metal member 10 for the unit and the coupling claw 4b are completed. By the biasing force due to the elastic deformation of, the pressing force in the direction toward the rear wall reinforcing sheet metal member 4 for the body is applied to the rear wall reinforcing sheet metal member 10 for the unit. As a result, the imaging unit 2 is pushed to the camera body 1. Further, even if the semi-circular convex portion 10s is in contact with the bent portion 4f of the engaging claw 4b, and there is a gap due to the dimensional error between the bent portion 4f and the unit rear wall reinforcement sheet metal member 10, The play caused by this dimensional error is absorbed by the elastic deformation of the leaf spring 2k and the semicircular convex portion 10s, as shown in FIG. In addition, in FIG. 27, the state before the elastic deformation of the leaf spring 2k is shown by the double-dot chain line.

[Explanation of Sliding Contact Ribs 4k, 4n of Resin Plate 30 and Supplementary Description of Configuration of Resin Plate 30]

The function of the sliding contact rib 4k is the same as that of the sliding contact rib 4n. Therefore, the function of the sliding contact rib 4n will be described here with reference to FIGS. 28 and 29.

When the imaging unit 2 is slid left and right to detach the imaging unit 2 from the camera body 1, the unit rear wall reinforcement sheet metal member 10 is attached to the body rear wall reinforcement sheet metal member 4. If the configuration is in direct contact, metal sounds are generated due to the metal photography between the back wall reinforcement sheet metal member 4 for the body and the back wall reinforcement sheet metal member 10 for the unit. However, according to this embodiment, when the imaging unit 2 is slid left and right with respect to the camera body 1, as shown in Figs. 28 and 29, the rear wall reinforcement sheet metal member 10 for the unit is Since it is the structure which slides to the left-right direction, sliding-contacts with the sliding contact rib 4n made of resin, generation | occurrence | production of the metal sound resulting from abrasion between metals can be prevented.

Moreover, as a structure which arrange | positions the resin plate 30 to the recess of the rear wall part 1B, when the imaging unit 2 is pushed to the rear wall part 1B, between the rear wall part 1B and the resin plate 30 Due to the dimensional tolerances, the resin plate 30 is elastically deformed and rolled up, and so-called "pulling sound" occurs due to the rolled-up of the resin plate 30. However, in this embodiment, as shown in FIGS. 25-29, several hemispherical protrusion 30t is formed in the appropriate position on the surface of the side which faces the rear wall part 1B in the resin plate 30. FIG. And absorbs the dimensional tolerances between the rear wall portion 1B and the resin plate 30, thereby preventing the buckling and elastic deformation caused by the dimensional tolerances. The occurrence of "gaping" is prevented.

As shown in FIG.

Here, power is supplied to the imaging unit 2 from the camera body 1. For example, the hall element 104, the drive coil 105, and the gyro sensor 106 constitute part of the image stabilization mechanism. The signal of the camera shake correction mechanism is input to the main CPU 208 via the connector terminals 116 and 201, and the main CPU 208 performs the camera shake correction process based on this signal. The camera shake correction process is a process of correcting the shake of the image projected on the light receiving surface of the image pickup device caused by the camera shake.

For example, the camera shake correction process may be a process of driving the imaging element in a direction opposite to the direction of the shake detected by the gyro sensor 106, or in the same direction as the direction of the shake detected by the gyro sensor 106. It may be a process of driving some optical elements of the imaging lens unit 107.

Alternatively, a configuration in which the main CPU 103 performs compression processing in a format such as JPEG and transmits the compressed image data to the main CPU 208 through the connector terminals 116 and 201 can be adopted. Therefore, the structure in which the imaging unit 2 performs image processing or compression processing can transmit the stable image with little noise to the main CPU 208 of the camera body 1. These electrical component parts are arrange | positioned at the electrical-base base mentioned later.

Therefore, according to the embodiment of the present invention, as shown in Figs. 1 and 2, the imaging unit 2 of different sizes can be attached and detached with respect to the same camera body 1. In addition, when the imaging unit 2 is attached to the camera body 1, the camera body 1 and the lower surface of the housing 2A of the imaging unit 2 are flush with the lower surface of the camera body 1. When the imaging unit 2 is configured, handling of the camera body 1 with the imaging unit 2 is facilitated. In addition, whenever the imaging unit 2 of a different size is attached to the camera body 1, when the lower surface of the housing 2A of the imaging unit 2 is comprised so that it may become coplanar with the lower surface of the camera body 1, Regardless of the size of the imaging unit 2 to be attached, handling of the camera body 1 becomes easy.

The recess 1A of the camera body 1 is open in three directions (right, bottom, front), so that the size constraint of the imaging unit 2 with respect to the camera body 1 is relaxed, so that the customer's need In accordance with this, a large high-sensitivity imaging element or a small imaging element can be arranged in the imaging unit 2, and the imaging unit 2 having different sizes in the right, left, up and down directions can be attached and detached to the common camera body 1. . In addition, since the degree of freedom of the size of the lens barrel 3 of the imaging unit 2 is increased, the imaging unit can be provided as an interchangeable lens group unit of various lenses ranging from a short focal lens to a high magnification zoom lens. Thus, the customer will purchase and upgrade only the imaging unit 2 as the imaging element 108 advances.

Since the recess 1A of the camera body 1 is open in two directions, the right side and the lower side, the imaging unit 2 having different sizes can be attached in the left, right, up and down directions. Therefore, since the restriction of the size of the imaging unit 2 with respect to the camera body 1 is relaxed, a large high sensitivity imaging element or a small imaging element can be arrange | positioned to the imaging unit 2 according to a customer's needs, An imaging unit 2 of different sizes having different lens barrels 3 or imaging elements can be attached or detached to the common camera body 1. In addition, since the degree of freedom of the size of the lens barrel 3 of the imaging unit 2 is increased, the imaging unit 2 can be provided as an interchangeable lens group unit of various lenses ranging from a single focal lens to a high magnification zoom lens. Thus, the customer will purchase and upgrade only the imaging unit 2 as the imaging element 108 advances.

According to the embodiment of the present invention, as described above, with respect to the same camera body, the lens barrel 3 or the plurality of imaging units 2 having different sizes of housing elements arranged in recesses and having different sizes are removed. can do. The lens barrel 3 of the imaging unit 2 shown in FIG. 2 is longer than the lens barrel 3 of the imaging unit 2 shown in FIG. 1, and the optical system is large. In addition, when the imaging unit 2 is attached to the camera body 1, the camera body (the lower surface 2e of the housing 2A of the imaging unit 2 and the lower surface of the camera body 1 are coplanar). It is preferable to constitute 1) and the imaging unit 2.

Therefore, since the recess 1A of the camera 1 is opened in three directions here, and the restriction | limiting of the size of the imaging unit 2 with respect to the camera body 1 is relaxed, it is large in accordance with a customer's needs. A high-sensitivity imaging element or a small imaging element can be arranged in the imaging unit 2, and the imaging lens 2 having different lens barrels 3 or imaging elements can be attached to or detached from the common camera body 1. . In addition, since the degree of freedom of the size of the lens barrel 3 of the imaging unit 2 is increased, the imaging unit can be provided as an interchangeable lens group unit of various lenses ranging from a short focal lens to a high magnification zoom lens. Thus, the customer will purchase and upgrade only the imaging unit 2 as the imaging element 108 advances. In addition, when a bay connector is used for the two connector portions 11 and 12, image data can be transmitted in a short time.

In addition, in the standard of the lens mount for interchangeable lenses, there are limitations on the size of the image pickup device, the distance (flangeback) in the optical axis direction between the lens mount and the image pickup device, the diameter of the lens mount, and the like. Four Thirds System). Due to this limitation, there was a limit to slimming / miniaturizing the camera as a whole.

In contrast, in the present invention, the size of the imaging device, the distance in the optical axis direction between the optical system and the imaging device, the diameter of the lens barrel, and the like can be freely set for each imaging unit. According to the use for each imaging unit, various optical systems and various kinds / sizes of imaging elements (type: COMS, CCD, etc., size: ASP-C, 2 / 3-inch type, 1 / 2.33 type, etc.) can be freely combined. .

In addition, in the case of slimming / miniaturizing the camera as a whole, since the length of the optical axis direction of the imaging unit 2 can be shortened and the diameter of the lens barrel can be reduced, the overall size of the imaging unit can be made small.

On the other hand, in order to improve the imaging performance of the camera can be combined with a large image pickup device and a large optical system, it is possible to improve the various imaging performance of the camera. Also in this case, since the degree of freedom of the combination of the optical system and the imaging device is high, and the optical system and the imaging device can be optimally designed, the overall size of the imaging unit can be reduced while improving the imaging performance. Moreover, according to a use, it is also possible to combine a large optical system and a small imaging element, or to combine a small optical system and a large imaging element.

In addition, since the imaging unit in which the camera is slimmed and downsized overall and the imaging unit in which the imaging performance of the camera is improved can be attached and detached to the same camera body, the entire imaging system composed of cameras having various characteristics can be made slim and compact. . That is, according to the present invention, the digital camera (imaging device) itself and the entire imaging system can be miniaturized, thereby improving portability.

In addition, since the 68-pin bay connector is used for the two connector portions 11 and 12 that communicate between the camera body 1 and the imaging unit 2, large-capacity image data can be transmitted in a short time. Alternatively, in order to communicate between the camera body 1 and the imaging unit 2, other methods, such as a wireless communication system, an optical communication system, a contact communication system that communicates by contact instead of fitting, or the like, may be used. Can be used.

In addition, the two connector portions 11 and 12 supply electric power to the imaging unit 2 from the camera body 1 (see FIG. 31). In this embodiment, since the two connector parts 11 and 12 supply not only communication but also electric power, problems hardly occur when the connector is unplugged or plugged in. However, the communication connector and the power supply connector may be provided separately.

Attachment Procedure of the Imaging Unit 2 to the Camera Body 1

The procedure of attaching the imaging unit 2 to the camera body 1 is outlined. In FIG. 32, the imaging unit 2 is moved in the direction of the negative side in the Z direction, thereby being set in the rear part 1B of the camera body 1.

Next, the camera body side connector part 12 and the imaging unit side connector part 11 are fitted by moving the imaging unit 2 to the negative direction (left direction) of an X direction.

In this state, when viewed in the left-right direction (XY direction), the engaging projection (angle regulating member) 4g is located between the side wall portion 1C and the pressing portion.

In the imaging unit 2, the imaging unit 2 is positioned in the X direction with respect to the camera body 1 in a state where the camera body side connector 12 and the imaging unit side connector 11 are coupled to each other. When the plus direction (right direction) is moved, the camera body side connector portion 12 and the imaging unit side connector portion 11 are disengaged.

Therefore, the direction in which the imaging unit 2 is attached or detached from the side wall of the side wall portion 1C of the camera body 1 is the X direction (left and right directions).

The procedure for setting the imaging unit 2 in the camera body 1 will be described in detail below.

The camera body 1 is placed in a horizontal state with the rear wall portion 1B of the camera body 1 downward. For example, the camera body 1 is placed in the left hand and placed in a horizontal state. The imaging unit 2 is moved closer to the camera body 1 from the arrow F1 direction shown in FIG. 32 (forward or backward direction or in the up and down direction in FIG. 32), and as shown in FIG. 33, the engaging projection 4g is moved. Opposed to the insertion opening 10i, the engaging claw 4b and the rectangular projection 4m are opposed to the guide groove 10q, so that the engaging claw 4b and the rectangular projection 4m enter the guide groove 10q. Then, the engaging projection 4g enters the insertion opening 10i. At the same time, the peripheral edges 10a and 10a of the unit rear wall reinforcement sheet metal member 10 are in sliding contact with the guide surfaces 4p and 4p of the unit rear wall reinforcement sheet metal member 10.

Thus, as shown in FIG. 33, a part of the peripheral edge 10a of the rear wall reinforcing sheet metal member 10 for the unit contacts the sliding contact ribs 4k and 4n. In this state, when the imaging unit 2 is moved in the direction of the arrow F2 shown in FIG. 33, the cut bent portion 4e of the engaging claw 4b is guided along the guide hole 10r for the engaged claw cut bent portion, and the unit A part of the engaging plate portion 10n of the back wall reinforcing sheet metal member 10 comes into contact with the sliding contact rib 4n. At the same time, the cut bent portion 4i of the engaging projection 4g is guided along the guide hole 10j for the engaging projection cut bent portion.

When the engaging claw 4b is guided along the inclined wall 10qs of the engaging plate portion 10n, the engaging claw 4b elastically deforms the leaf spring 2k, and with an elastic deformation force applied to the leaf spring 2k. As a result, the rear wall reinforcing sheet metal member 10 for the unit is pushed against the rear wall portion 1B. Thereby, rattling due to the dimensional error between the imaging unit 2 and the camera body 1 is absorbed.

Further, while the plate surface of the rear wall reinforcing sheet metal member 10 for the unit slides on the sliding contact ribs 4k and 4n made of resin, the peripheral edges 10a and 10a of the rear wall reinforcing sheet metal member 10 for the unit Since the imaging unit 2 is guided toward the side wall portion 1C while the sliding surfaces are in sliding contact with the guide surfaces 4p and 4p, the rear wall reinforcement sheet metal member 10 for the unit and the rear wall reinforcement sheet metal member 4 for the body 4 Metal abrasion generated by abrasions of the axle is also avoided.

When the engaging claw 4b comes into contact with the leaf spring 2k, at about the same time, the fitting of the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 starts, and the auxiliary fitting protrusion 14 and the auxiliary fitting hole ( 22), the regulation of the position of the imaging unit side connector part 11 with respect to the camera body side connector part 12 is roughly performed.

Then, as shown in FIG. 22, the camera body side connector portion 12 and the imaging unit side connector portion 11 are fitted to each other, and the camera body 1 and the imaging unit 2 are electrically connected so as to be able to communicate. do.

The main CPU 208 of the camera body 1 monitors whether or not a predetermined pin (camera body side connection detecting pin) of the camera body side connector portion 12 is connected. When detecting that the camera body side connection detecting pin is connected to the imaging unit side connection detecting pin, communication and power transmission between the camera body side connector portion 12 and the imaging unit side connector portion 11 are started.

Alternatively, when the main CPU detects that the connection detecting pin is connected, the communication and power transmission between the camera body side connector 12 and the imaging unit side connector 11 may be immediately started. .

Alternatively, when the main CPU detects that the connection detecting pin is connected, communication or power transmission is performed between the camera body side connector portion 12 and the imaging unit side connector portion 11 after a predetermined time has elapsed. It may be a starting configuration. That is, the connection of the imaging unit side connector part 11 and the camera body side connector part 12 only needs to make the state which communication is possible, and it is not necessary to communicate simultaneously with a connection.

Moreover, since the shock absorbing member 22a is provided in the bottom of the auxiliary fitting hole 22, when the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 are fitted, the camera body 1 and the imaging unit 2 The shock caused by the collision of) is alleviated. In addition, the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 can further alleviate rattling in the front-back direction of the imaging unit 2 with respect to the camera body 1.

When the connection between the camera body side connector portion 12 and the imaging unit side connector portion 11 is completed, as shown in FIGS. 24 to 29, the engagement claw 4b is adapted to apply the elastic pressing force of the leaf spring 2k. The semi-circular convex portions 10s and 10s are in contact with each other.

At the same time as when the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 are fitted, and immediately before the positioning protrusion and the positioning hole 63 are fitted, the inclined wall 20e of the locking target claw 20d is provided. ) Is in contact with the inclined wall 25c 'of the locking claw 25c, and the component force generated in the inclined wall 25c' becomes larger than the rotational pressing force of the locking plate 25 by the pressing member (not shown). Reference numeral 25 is rotated in a direction opposite to the direction in which the rotational pressing force acts (direction of arrow F3 in Fig. 14) with the spindle 27 as a supporting point.

Subsequently, when the locking object claw 20d passes over the locking claw 25c, the locking plate 25 returns to its original position by the rotational pressing force. As a result, the locking claw 25c enters the notch portion 20c, and the locking target claw 20d enters the notch portion 25b. As a result, the locking claw 25c and the locking target claw 20d are engaged with each other, and the imaging unit 2 is locked to the left and right directions with respect to the camera body 1. The rattling of the camera body 1 and the imaging unit 2 is restricted by the locking claw 25c as the locking member and the locking target claw 20d as the locking target member.

In this embodiment, a pair of engaging claws 4b and 4b are reliably coupled to the engaging plate portions 10n and 10n while the imaging unit 2 is locked to the camera body 1. Since the pair of coupling plate portions 10n and 10n are formed at positions away from the left and right directions with respect to the pair of auxiliary fitting protrusions 14 and 14 formed on the side wall portion 1C, the imaging unit 2 is connected to the camera body 1. When withdrawing from the front side), the force due to the withdrawal is dispersed, and withdrawal is reliably prevented. In addition, it is possible to prevent the excessive force accompanying the drawing out from being applied to the two connector portions 11 and 12.

Moreover, even when it tries to take out the lower side part of the right side of the imaging unit 2 by hand, and forcibly pulls it out to the lower right side, a pair of auxiliary fitting protrusions 14 and 14, a pair of engaging claws 4b and 4b, and a locking mechanism ( Withdrawal is prevented by 24), and the excessive force accompanying this release is prevented from being applied to the two connector portions 11 and 12.

In addition, by one operation of moving the imaging unit 2 toward the side wall portion 1C, the mechanical fixing of the camera body 1 and the imaging unit 2 by the locking mechanism 24, and the two connector portions Since electrical connection of (11, 12) is completed almost simultaneously, the attachment operation to the camera body 1 of the imaging unit 2 can be performed easily in a short time.

In addition, regardless of the camera body side connection detection pin of the camera body 1, the timing of fitting the two connector parts 11 and 12 is the timing of communication and power transmission / reception start of the two connector parts 11 and 12. You can do this differently.

For example, an operation unit (not shown) instructing the start and end of communication and power transmission / reception by the two connector units 11 and 12 is provided in the camera body 1, and the two connector units ( 11 and 12 may be configured to start / end communication and power transmission / reception.

Alternatively, after providing a locking state detection unit for detecting the position of the locking plate 25, the locking state detection unit detects that the imaging unit 2 is locked at a predetermined position of the locking plate 25, and then the two connectors The units 11 and 12 may be configured to start / end communication and power transmission / reception.

Further, when the bent portion 4f of the pair of engaging claws 4b is in contact with the engaging plate portion 10n on the outside of the imaging unit 2 (when the bent portion 4f is placed on the engaging plate portion 10n), Since the bent portion 4h is in contact with the component wall portion 10h 'outside the imaging unit 2, as shown in FIG. 34, the rear wall reinforcing sheet metal member 4 for the body of the rear wall portion 1B is provided. On the other hand, the imaging unit 2 floats in parallel, for example, and the imaging unit 2 is prevented from tilting with respect to the camera body 1, and the camera body side connector portion (with the imaging unit 2 inclined) is prevented. 12) and the imaging unit side connector part 11 are prevented from connecting.

In addition, in this embodiment, since the positional relationship of the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 is offset, mutual connection of the two connector parts 11 and 12 can be reliably prevented. As a result, destruction of the two connectors 11 and 12 is reliably prevented.

In other words, the engaging projection 4g is provided when the imaging unit 2 is placed in the recess 1A and attached to or detached from the camera body 1, and the imaging unit side connector portion 11 and the camera body side connector portion ( At the time of connecting 12, the imaging unit 2 functions as an unnatural posture and an angle avoiding member (angle restricting member) which prevents the imaging unit 2 from being connected to the camera body 1 at an unnatural posture and angle.

The engaging projection 4g also serves to prevent the opening 52 formed in the side wall portion 1C of the camera body 1 and the connector cover portion as the fitting protrusion of the imaging unit 2 from being obliquely fitted.

In other words, the angle regulating member (regulating member) prevents the imaging unit side connector portion 11 and the camera body side connector portion 12 from being connected in an unnatural posture and angle. When the regulating member is inserted into the insertion opening, the rear surface of the imaging unit 2 and the rear wall portion 1B of the camera body 1 contact each other in parallel, and the imaging unit 2 faces the side wall portion 1B. As it moves in the direction, the imaging unit side connector portion 11 and the camera body side connector portion 12 are connected.

In addition, when the regulating member contacts the regulating member contacting portion, the rear surface of the imaging unit 2 and the rear wall portion 1B of the camera body 1 do not contact with each other in parallel with each other. The camera body side connector portion 12 is not connected.

Further, the angle restricting member can prevent the imaging unit side connector portion 11 and the camera body side connector portion 12 from being connected in an unnatural posture and angle irrespective of whether the pressing portion is present.

In addition, in this embodiment, the press part which presses the imaging unit 2 toward the rear wall part 1B of the camera body 1 in the state in which the imaging unit 2 was attached to the camera body 1 is a camera body. Since it is provided in (1), a problem may arise in which the imaging unit 2 is attached to the camera body 1 at an unnatural angle. In this embodiment, since the angle restricting member is provided, the problem of mounting the imaging unit 2 and the camera body 1 at an unnatural angle and posture can be reliably prevented.

The height from the rear wall surface of the rear wall portion 1B to the bent portion 4h of the engaging projection (angle regulating member) 4g is from the rear wall surface of the rear wall portion 1B to the curved portion 4f of the coupling claw 4b. If it is equal to or larger than the height, the imaging unit 2 can be prevented from being connected to the camera body 1 in an unnatural posture and angle.

On the other hand, when the height from the rear wall surface of the rear wall portion 1B to the bent portion 4h of the engaging projection (angle regulating member) 4g is lowered, the engaging projection guide hole 10h corresponding to the engaging projection 4g is made shallow. It is possible to reduce the size of the imaging unit 2.

Therefore, the engaging projection (angle regulating member) 4g is disposed at a position closer to the camera body side connector portion 12, that is, at a position closer to the side wall portion 1C than the pressing portion. In this way, when the engaging projection (angle regulating member) 4g is disposed at a position closer to the camera body side connector portion 12, a pair is obtained even if the height of the engaging projection 4g is lower than the height of the engaging claw 4b. Camera body 1 of the imaging unit 2 when the bent portion 4f of the coupling claw 4b is in contact with the engaging plate portion 10n and the bent portion 4h is in contact with the component wall portion 10h '. The inclination angle with respect to can also be made small. That is, since the imaging unit 2 can be brought closer to the rear wall reinforcing sheet metal member 4 for the body of the rear wall portion 1B in parallel, even if the height of the engaging projection (angle regulating member) 4g is lowered. The imaging unit 2 can be prevented from being connected to the camera body 1 at an unnatural posture and angle.

Now, the procedure for detaching the imaging unit 2 from the camera body 1 will be described.

When the imaging unit 2 is viewed from the front in the state where the imaging unit 2 is disposed in the recess 1A, the unlocking button 26d is operated in the right direction (F4 direction in FIG. 1). Accordingly, the unlocking operation member 26 is rotated in the opposite direction (the opposite direction to F3 in Fig. 14) of the rotational pressing force of the unlocking spring 28 with the spindle 27 as a supporting point.

In this way, the release protrusion 26b is in contact with the side surface 25f of the locking plate 25. By rotating the release projections 26b in a direction opposite to the rotational pressing force of the unlocking spring 28 (the direction opposite to F3 in Fig. 14), the locking plate 25 has the notch portion 20c with the spindle 27 as a supporting point. It rotates in the retreat direction (rear) from (). As a result, the engagement between the locking claw 25c and the locking target claw 20d is released.

In other words, the locking of the imaging unit 2 with respect to the camera body 1 is released. In this state, the imaging unit 2 is moved with respect to the camera body 1 from the left to the right direction (in the arrow F5 direction in FIGS. 1 and 2). By doing so, not only the fitting of the two connector parts 11 and 12 is released, but also the fitting of the auxiliary fitting protrusion 14 and the auxiliary fitting hole 22 is also released.

Until the notch wall 10b of the imaging unit 2 contacts the rectangular projection 4m, the imaging unit 2 is moved from the left to the right direction (arrow F5 in FIGS. 1 and 2 and arrow F2 in FIG. 33). In the opposite direction). Thereafter, the imaging unit 2 is moved in a direction away from the rear wall portion 1B (the opposite direction to F1 in FIG. 32). Thus, separation of the imaging unit 2 from the camera body 1 is completed. In addition, when the user releases his finger from the unlocking button 26d, the unlocking operation member 26 returns to its original position by the pressing force of the unlocking spring 28. In addition, the locking plate 25 also returns to its original position due to the rotational pressing force (not shown).

As described above, in this embodiment, the photographer holds the grip portion 1c with his right hand, places the upper wall portion 1D on the upper side, and points the lens system toward the subject in front of the normal use state. do. In this normal use state, the right direction that is difficult for the user to find and operate is the release operation direction. Therefore, in the state where the user grips the grip portion 1c normally, the imaging unit 2 causes the camera body ( The risk of falling off from 1) can be reduced.

[Procedures for Attaching Imaging Unit 2 to Camera Body 1]

Now, the procedure for setting the imaging unit 2 in the camera body 1 will be described in detail.

In Embodiment 2, the camera user grasps the imaging unit 2 by hand, and the rear wall reinforcement sheet metal member for the unit is attached to the rear wall reinforcement sheet metal member 4 for the body provided in the rear wall portion 1B of the camera body 1. The relative positional relationship of the imaging unit 2 with respect to the camera body 1 is set so that 10) becomes substantially parallel.

Then, the peripheral edges 10a and 10a of the rear wall reinforcing sheet metal member 10 for the unit are positioned along the guide surfaces 4p and 4p of the guide protrusions 4j and 4j, and the rear wall reinforcing sheet metal member 4 for the body is placed. The user of the camera moves the imaging unit 2 relative to the camera body 1 to the side wall portion 1C of the camera body 1 with the) facing parallel to the rear wall reinforcing sheet metal member 10 for the unit. The image pickup unit 2 is attached to the camera body 1 by sliding toward.

That is, the camera body 1 is placed in a horizontal state with the rear wall portion 1B of the camera body 1 downward. For example, the camera body 1 is placed in the left hand and placed in a horizontal state. The imaging unit 2 is moved close to the camera body 1 in the direction of arrow F1 'shown in FIG. 37G, so that the engaging projection 4g is inserted into the insertion opening 10i near the open end component wall portion 10h " The protrusion guide groove 2s is faced, and the guide protrusion 4j, the rectangular protrusion 4m, and the engaging claw 4b face the guide groove 10q.

Next, the imaging unit 2 is slid toward the side wall portion 1C. 37H, 37I and 37J, the peripheral edges 10a and 10a of the rear wall reinforcing sheet metal member 10 for the unit are provided on the guide surfaces 4p and 4p of the guide protrusion 4j during the slide operation.

Assuming that protrusions 10a 'and 10a' are not provided at the peripheral edges 10a and 10a of the rear wall reinforcing sheet metal member 10 for the unit, the bottom wall 10p from the bent portion 4f of the coupling claw 4b. The clearance gap H is smaller than the clearance gap H when the band-shaped protrusions 10a 'and 10a' are provided. At this time, if the imaging unit 2 is inclined with respect to the camera body 1 and the bent portion 4f of the guide claw 4b is directly hit by the bottom wall 10p due to the slight manipulation of the camera user, The clearance gap H cannot be secured, the bottom wall 10p can be wound by the coupling claw 4b, and the operation quality at the time of attaching and detaching the imaging unit 2 with respect to the camera body 1 falls. Can be.

However, in Embodiment 2, since the protrusion part 10a ', 10a' is provided in the peripheral edge 10a, 10a of the back wall reinforcement sheet metal member 10 for units, it is bottomed out from the bent part 4f of the coupling claw 4b. The gap H up to the wall 10p can be secured, and even if the imaging unit 2 is inclined with respect to the camera body 1 due to slight manipulation of the camera user, the bottom wall 10p does not injure the wound. You can surely prevent wearing.

In particular, in order to increase the space inside the housing 2A without increasing the overall thickness of the housing 2A (thickness in the Z direction), even if the depth of the guide groove 10q of the rear portion 2b is made shallow, When the imaging unit 2 is attached to or detached from the body 1, the bottom wall 10p can be prevented from being injured.

If the imaging unit 2 is further moved in the direction of the arrow F2 shown in Figs. 37H and 37I, the band-like protrusions 10a 'and 10a' are placed on the sliding contact ribs 4k on the side close to the sliding contact ribs 4n. In the contacted state and in the state that the peripheral edges 10a and 10a of the rear wall reinforcing sheet metal member 10 for the unit are in sliding contact with the guide surfaces 4p and 4p of the guide protrusion 4j, the engaging projection 4g Is guided from the insertion opening 10i near the open end constituent wall portion 10h " toward the guide hole 10j for the engaging projection cut bent portion inward.

As shown in Fig. 37K, when the edge 4gs of the engaging projection 4g reaches near the position of the inclined wall 10ij, the right edge 4b 'of the engaging claw 4b is the rear wall reinforcement sheet metal for the unit. The position vicinity of the inclined wall 10qs of the member 10 is reached. Then, as shown in Figs. 37K and 37L, the banded protrusions 10a 'and 10a' enter the banded protrusion escape recess 4k '. As a result, the outer surface of the rear wall reinforcing sheet metal member 10 for the unit is in sliding contact with the sliding contact ribs 4k and the sliding contact ribs 4n on the side close to the sliding contact ribs 4n.

Further, the bent portion 4f of the engaging claws 4b and 4b is close to the bottom wall 10p of the guide groove 10q, and the bent portion 4h of the engaging projection 4g is the bottom of the engaging projection guide groove 2s. It is close to the wall, so that the back wall reinforcing sheet metal member 10 for the unit can enter between the bend 4f, the bend 4h and the back wall reinforcing sheet metal member 4 for the body.

Further, the left and right edges of the band-shaped protrusions 10a 'and 10a' in the direction in which the band-shaped protrusions 10a 'and 10a' extend are inclined, and correspondingly, the sliding contact ribs 4k and 4k and the band are correspondingly. Since the portion between the protrusions for evacuating the protrusion 4k 'is inclined, the band protrusions 10a', 10a 'smoothly enter or retract from the band protrusions for evacuation recess 4k'. .

As shown in Fig. 37K, the edge 4gs of the engaging projection 4g reaches near the position of the inclined wall 10ij, and the right edge 4b 'of the engaging claw 4b is the rear wall reinforcement sheet metal for the unit. After reaching the vicinity of the position of the inclined wall 10qs of the member 10, the imaging unit 2 is further moved in the direction of the arrow F2 shown in Figs. 37K and 37L. Then, the engaging claw 4b in a state in which the outer surface of the rear wall reinforcing sheet metal member 10 for the unit is in sliding contact with the sliding contact ribs 4k and the sliding contact ribs 4n on the side close to the sliding contact ribs 4n. Cutting bent portion 4e is guided along the guide hole 10r for the coupling claw cut bent portion. At the same time, the cut bent portion 4i of the engaging projection 4g is guided along the guide hole 10j for the engaging projection cut bent portion. Further, the bent portion 4f of the engaging claw 4b faces the inner surface of the engaging plate portion 10n, and the bent portion 4h of the engaging protrusion 4g is the bending of the engaging projection cutoff of the back wall reinforcing sheet metal member 10 for the unit. It faces the inner surface of the component wall part of the bouillon guide hole 10j.

Then, through the same operation procedure as in the first embodiment, the bent portion 4f of the engaging claw 4b comes into contact with the semicircular convex portions 10s and 10s while being subjected to the elastic pressing force of the leaf spring 2k. Further, in the state where the bent portion 4f of the engaging claw 4b is in contact with each of the semicircular convex portions 10s and 10s, as shown in Figs. 37M and 37O, the engaging projection 4g is for the engaging projection cutting bent portion. It is located at the end of the guide hole 10j.

Thus, according to the imaging device which has the structure of Embodiment 2, since the guide groove 10q of the imaging unit 2 and the engaging projection guide hole 10h are open toward the imaging unit side connector part 11 side, By sliding the imaging unit 2 in the horizontal direction with respect to the camera body 1, the imaging unit 2 can be attached to the camera body 1, and the attaching operation can be further facilitated.

[Procedures for separating the imaging unit 2 from the camera body 1]

Subsequently, the procedure of separating the imaging unit 2 from the camera body 1 is almost the same as in the first embodiment. To further explain, when the imaging unit 2 is moved from the left to the right direction (in the direction of the arrow F5 in FIG. 37M) with respect to the camera body 1, the outer surface of the rear wall reinforcing sheet metal member 10 for the unit is made of resin. The back wall for the unit, while slidingly contacting the sliding contact ribs 4k, 4k, 4n of the band, and the banded projections 10a ', 10a' are guided to the banded projection escape recesses 4k ', 4k'. The reinforcement sheet metal member 10 moves from left to right with respect to the camera body 1. Thus, as shown in Fig. 37K, the right edge portions of the band-like protrusions 10a 'and 10a' reach the position just before the sliding contact ribs 4k on the right side.

At this time, as shown in Fig. 37K, the edge 4gs of the engaging projection 4g reaches a position when it is spaced apart from the inclined wall 10ij or just before being spaced apart. Further, the right edge 4b 'of the engaging projection 4b has reached a position when it is spaced apart from the inclined wall 10qs of the rear wall reinforcing sheet metal member 10 for the unit or just before being spaced apart.

That is, the engaging projection 4g is separated from the guide hole 10j for the engaging projection cutting bent portion, and the engaging claw 4b is separated from the guiding hole 10r for the engaging claw cutting bent portion.

Thereafter, when the imaging unit 2 is moved from the left to the right with respect to the camera body 1, the band-shaped protrusions 10a ', 10a' are slid in contact with the sliding contact ribs (as shown in FIGS. 37H and 37I). The sliding contact rib 4k on the side close to 4n) is raised.

Thus, when the band-shaped protrusions 10a ', 10a' of the rear wall reinforcing sheet metal member 10 for the unit rides up the sliding contact ribs 4k on the side close to the sliding contact ribs 4n, the engagement claws 4b The clearance gap H from the bend part 4f of () to the bottom wall 10p of the back part 2b increases. As a result, when detaching the imaging unit 2 from the camera body 1, as long as the bottom wall 10p of the rear part 2b can be damaged to some extent by the bent part 4f of the coupling claw 4b. It is certainly prevented.

In the second embodiment, since the guide groove 10q and the engaging projection guide hole 10h of the imaging unit 2 are opened toward the imaging unit side connector portion 11 side, the imaging unit 2 is kept as it is. By sliding from the left to the right in parallel with respect to the body 1, the imaging unit 2 can be separated from the camera body 1.

Therefore, according to the second embodiment, not only the attaching operation but also the detaching operation can be further facilitated.
